Answer:
The minimum concentration of acetaminophen that can be detected by new= 10μg/mL
Volume of blood sample=2ml
Minimum mass of acetaminophen that can be detected by automated system= 10×2= 20μg= 0.020mg
Answer:
The vocabulary terms are in the correct order.
Explanation:
The substances that undergo chang are called <em>reactants</em>. They are what create the products. Reactants are on the left side of the equation while the products are on the right side of the equation. The new substances are called <em>products</em>. In other words, what is produced? The products are produced. The reactant that will be used up first is called a <em>limiting reactant</em>. Why? Because it is what limits the reaction. It determines how much products can be made. The reactant that is left over then, is called the <em>excess reactant.</em> That is what is left in excess and does <u>not</u> determine how much product is made.
In
Methyl Amine the Nitrogen atom is attached to two Hydrogen Atoms and one Methyl (CH₃-) group. From
Lewis structure it is shown that the Nitrogen atom also contains a
lone pair of electron.
So,
According to
Valence Shell Electron Pair Repulsion (VSEPR)
Theory, those central atoms which have four electron pairs and all of them are bonding electron pairs gives
Tetrahedral Geometry.
Methylamine also contains four electron pairs, but out of four only
three are bonding pair electrons and
one lone pair electron. Now, due to presence of lone pair of electron (which has
greater repulsion effect than bonding electron pair) the bond angle between H-N-H will decrease from
109° to 107° and results in the formation of <span>
Trigonal Pyramidal geometry as shown below,</span>
Answer:
A covalent chemical bond is one in which <u>outer-shell electrons of two atoms are shared so as to satisfactorily fill their respective orbitals</u>.
Explanation:
Covalent bonds are formed between two atoms having their electronegativity difference less than 1.7. In this type of bonding the valence electrons of one atoms forms molecular bond with the valence electrons of another atom. The electrons are mutually shared.
Covalent bond can be non-polar as for example formed between hydrogen and carbon atoms.
Also, covalent bond can be polar in nature as that formed between hydrogen and chlorine atoms because the chlorine atom is more electronegative and hence attracts the electrons more towards itself making density of electrons less on hydrogen atom.
A dipole-dipole interaction is a force of attraction between slightly positive hydrogen on one molecule and a slightly negative atomon another molecule while ion-dipole interaction is force between an ion and a polar molecule
